Answer:
Transduction is a process by which DNA is transferred from one bacterium to another by the action of a virus. It is also used to designate the process by which exogenous DNA is introduced into a cell by a viral vector. This is a tool that molecular biologists usually use to introduce a foreign gene in a controlled way into the genome of a recipient cell.
Explanation:
When bacteriophages (viruses that infect bacteria) infect a bacterial cell, their normal mode of reproduction consists in capturing and using the machinery of replication, transcription, and translation of the recipient bacteria cell to produce large numbers of virons, or produce particles. viral, including viral DNA or RNA and protein coat.
A change in the color of a substance -- this one is indeed a chemical change. Think of iron, if iron turns reddish, it's a completely different substance.
"Viruses straddle the definition of life. They lie somewhere between supra molecular complexes and very simple biological entities. Viruses contain some of the structures and exhibit some of the activities that are common to organic life, but they are missing many of the others. In general, viruses are entirely composed of a single strand of genetic information encased within a protein capsule. Viruses lack most of the internal structure and machinery which characterize 'life', including the biosynthetic machinery that is necessary for reproduction. In order for a virus to replicate it must infect a suitable host cell".

Answer:A
Explanation:
A fixed pulley raises the load in a unidirectional manner... This therefore reduces the force required to raise that same load without the pulley.. It actually reduces the force required to raise objects
